Getting #550 5.7.1 Recipient rejected (R1) when sending from new Exchange 2007 server

I have just installed a new server MS SBS 2008 and have set up Exchange 2007. I am able to receive all emails but when I try to send Im getting rejected:

#550 5.7.1 Recipient rejected (R1) ##

That is how emails bounced back from any server that I send. I did have a SBS 2003 with exchange at the same location so Im sure it is not a Reverse DNS issue. I did check for blacklists but that is not the case here either. I wonder if there is something on the configuration of the server itself that could be causing this.

Here is the detail email that I get:

Delivery has failed to these recipients or distribution lists:

The only thing that I see strange is that is using the .local server to go out, maybe I need to change it to go out with .com but I dont know how to do that.

Anyone has any ideas?

you need to make the .com address the default in recipient policy.

i presume you are sending out the same way as before, either via dns or smtp relay

Have you got Reverse DNS configured on your Fixed IP Address correctly and does the FQDN you use on your Fixed IP Address resolve back to the fixed IP Address?

e.g., Reverse DNS of mail.domain.com and a fixed IP of and mail.domain.com resolves in DNS to IP

Does your SEND connector FQDN also say mail.domain.com or mail.domain.local?  If it is .local - that is wrong - the name on the SEND connector needs to resolve in DNS back to your IP Address also.

If you want a definitive answer - drop me an email to alan @ it-eye.co.uk - I will see what my spam filter makes of you : )

Chris, I do have the .com as the default policy and when I create a new user it is using the right domain with the .com

What I did notice is that on the Accepted Domains I have the .com and the .local
The .com is the default one and it is Authorative too
The .local is no the the deault but it is authorative too

Should I remove the .local as an accepted domain or is that being used for local users?

Alan, the reverse DNS was working fine before and I double checked and it is ok now too.

My send connector had a blank space on the FQDN and added the mail.domain.com but no luck... disabled it and enabled it just in case but same error.

Any other ideas?

Okay - did you run the "Connect to the Internet Wizard" and "Fix My Network Wizard" when you setup SBS?  If you did - all should be set properly.

Remember - with SBS - there is usually a Wizard for everything so they should be used.  Don't manually tinker with the settings (removing .local etc) - it might not like it.
